How long do the fatigue and "brain fog" last after general anesthesia for surgery? It depends - on your age, the specific drugs used, how long the surgery took and how healthy you were to start with. These days, most general anesthesia is short-acting, which means you wake up quickly and the drugs are mostly out of your system within a few hours, said Dr. Carl Rosow, an anesthesiologist at Massachusetts General Hospital. But tiny amounts can linger for up to seven days - enough so that you may not feel completely normal, especially if you also have a drink or two. Moreover, if you are one of the unlucky 20 percent to 40 percent of patients who have nausea and vomiting after general anesthesia, that can add considerably to your recovery time because of dehydration and weakness from not eating, said Dr. John Ulatowski, director and chair of the department of anesthesia and critical care at Johns Hopkins Medical Institutions.

Injured Orioles third baseman Manny Machado was in the Orioles' clubhouse Wednesday and promised to return in late October if his teammates make it to World Series. "I'll be back, for sure," said the 21-year-old Machado, who has been in Los Angeles rehabbing since he had surgery on Aug. 27 to repair a partially torn ligament in his right knee. He arrived in Baltimore on Monday and said he will stay for the two games at Camden Yards before leaving Saturday for the club's spring training complex in Sarasota, Fla. to continue his rehab.

Lefty Tsuyoshi Wada had season-ending elbow-ligament (Tommy John) surgery Friday in California. Dr. Lewis Yocum, who removed bone spurs from Wada's elbow in 2007, performed Friday's surgery. The Orioles issued the following statement from Wada: “The procedure went as planned and Dr. Yocum felt good about how it went. He predicts a full recovery,” Wada said. “I'm glad to have this over with and look forward to beginning my rehabilitation so I can get back to pitching for the Orioles as soon as possible.” There is no set timetable on when he will return to Sarasota, Fla., to begin his rehab.

Although Ravens left tackle Eugene Monroe said his arthroscopic knee surgery went well last week, he was noncommittal on when he'll return to practice. Monroe declined to say if he completely tore or partially tore his meniscus and said he has no timetable on when he'll be able to run again. Monroe is expected to miss roughly a month, according to a source. "It just depends," Monroe said. "I'm doing everything I can to get back as soon as it's possible. I just come in and work every day to get healthy.

Oilers goaltender Nikolai Khabibulin will have surgery Thursday to repair a herniated disc in his back and is expected to be out 12 weeks. The Oilers didn't provide a timeline for his return, saying Wednesday that he's "out indefinitely," but Khabibulin's agent, Jay Grossman , said the goalie will need 12 weeks to recover. Khabibulin, who signed a $15 million, four-year contract over the summer, hasn't played since Nov. 16. He's 7-9-2 with a 3.03 goals-against average.

Wilson Betemit will not need surgery on his right wrist, which he reinjured during batting practice Friday in Oakland, according to Showalter. Betemit saw a hand specialist in Sarasota on Monday, who determined from tests that Betemit, who was on the disabled list in August with a similar wrist injury, is just dealing with inflammation. “They didn't feel like he needed surgery. That was good news,” Showalter said. “So he is going to probably get [a cortisone] injection and wait for the inflammation to go down.” Betemit is likely out for the season, but Showalter was not ready to concede that yet, preferring to see how quickly the inflammation subsides.

Yankees left-hander CC Sabathia will undergo arthroscopic surgery at a New York hospital Friday to correct a small meniscus tear in his right knee. Sabathia is scheduled to begin his regular routine in preparation for spring training three to six weeks after the surgery. In the meantime, manager Joe Girardi reportedly has begun to talk with the Yankees about the parameters of a new three-year contract for between $9 million and $10 million. And the Yankees declined to pick up the options of Lance Berkman ($15 million)

The general belief is that players recovering from hamate bone surgery -- as Nick Markakis is now -- have a short recovery time, but it can take a while for them to regain their full power at the plate. But a glance at some notable cases shows players can return to form farily quickly from the wrist injury . Boston Red Sox second baseman Dustin Pedroia played the final two months of the 2007 season (including the team's run to the World Series) with a cracked hamate bone in his left wrist.

Johns Hopkins University President Ronald J. Daniels will return to work full-time next week after two months of recuperation from surgery to remove a tumor from his abdomen. It was not malignant and Daniels, 50, did not have to undergo follow-up therapy after his October surgery. A seven-hour surgery to remove part of Daniels' pancreas, called a Whipple procedure, was deemed a success at the time, and his recovery took about as long as expected. Daniels, who became the university's 14th president in March, worked part-time in December.

The WWE announced Saturday that Roman Reigns underwent emergency surgery for an incarcerated hernia. He will not compete against Seth Rollins on Sunday night.

Minor league catcher Alex Murphy, who injured his left shoulder Aug. 15 while diving back to second base on a pickoff play, will undergo left shoulder surgery next week, Orioles manager Buck Showalter said Thursday. Murphy, who was selected out of Calvert Hall in the sixth round of the 2013 first-year player draft, was batting .277 with three home runs, 15 doubles, and 25 RBIs in 54 games for short-season Single-A Aberdeen. Showalter said Murphy will miss the Fall Instructional League in Sarasota, Fla., but he will be ready for spring training.

Manny Machado had the partially torn ligament in his right knee repaired successfully Wednesday morning, and the third baseman remains on the timeline to return to the club for spring training next season, according to Orioles manager Buck Showalter. The operation was performed at 6 a.m. in Los Angeles by surgeon Dr. Neal ElAtrrache, who did a similar procedure last October on Machado's left knee. “Doctors said everything went well, as expected,” Showalter said. “They had what they thought was going to happen, what they thought they were going to find.” Showalter said Machado will stay in Los Angeles to do his initial recovery for about three weeks, as originally planned.

Manny Machado's decision to have surgery on his right knee already has ended his season, and the timing of the procedure -- and its recovery -- might prevent the third baseman from being with the Orioles through the end of the regular season. Scheduled to have season-ending surgery Wednesday in Los Angeles to repair a partially-torn medial patellofemoral ligament in his right knee, Machado might not be back to support his teammates until a possible postseason game. Machado will fly to the West Coast on Tuesday for the procedure, which will be performed by Los Angeles Dodgers team orthopedist Dr. Neal ElAttrache, the same doctor who did the same procedure on his left knee last year.

CHICAGO - Once an MRI revealed a partially torn ligament in his right knee, Orioles third baseman Manny Machado knew it was possible that his season was over. But with the Orioles on the verge of their first American League East title in 17 years, Machado hoped rest and treatment would resolve the injury quickly enough to allow him to be a part of a possible postseason run. Nearly two weeks after his right knee buckled after following through on a swing, however, Machado has decided to have season-ending surgery for the second straight season.

D.C. United goalkeeper Josh Wicks underwent successful surgey on his right knee, the team announced. Wicks, who had shoulder surgery on Oct. 29, is not expected to miss more than the original four to six months. He recorded five shutouts and posted a 1.4 goals against average on the year.

Howard County executive Ken Ulman was recuperating at home Monday after surgery Friday to cauterize an artery in his nose that ruptured, causing a massive nosebleed, according to Kevin Enright, his spokesman. The 35-year old executive had scheduled this week off before the incident, his second attempt to take a break since a February family vacation was canceled due to the heavy snowstorms. Enright said Ulman returned home Saturday, after two nights at Howard County General Hospital.

CHICAGO - Here's a complete transcript of what Orioles third baseman Manny Machado had to say before today's game against the Chicago Cubs regarding his decision to undergo season-ending surgery to repair a partially torn medial patellofemoral ligament in his right knee. Machado said he hopes to have the procedure done next week in Los Angeles. On when he knew surgery could be a possibility: From the get-go, we knew it was partially torn, so it was in the back of my mind.

With news that Orioles third baseman Manny Machado is having surgery on his right knee and will be lost for the season, two questions immediately arise. How will this affect Machado long-term and how will this affect the Orioles short-term? Frankly, both are legitimate concerns. This will be Machado's second surgery in less than a year - one on each knee. It's his third serious injury in a little more than three years. The good news is that he is 22, he is in his physical prime and, at this age, his recuperative powers are about as heightened as they are going to get. It's much tougher to come back from knee surgeries at an advanced age. The bad news is the same.
